Abstract
The utility model discloses an integral type well cover steel frame, which comprises latticed reinforcing rib layers. The integral type well cover steel frame is characterized in that pluralities of corrugated reinforcing ribs are disposed between the reinforcing rib layers, the wave crest and the wave trough of the reinforcing ribs are respectively connected with the reinforcing rib layers to form a corrugated shock absorption layer. The integral type well cover steel frame employs multiple layers to reinforce, and combines with a shock absorption structure, thereby solving the problem that the existing well cover is low in shock resistance, the integral type well cover steel frame is strong in impact resistance, can add further frame layers according to practical situation when being shaped, and is flexible in assembling.
Description
Technical field
The utility model relates to the manhole well lid in a kind of urban construction, relates in particular to a kind of monolithic well lid steel frame.
Background technology
The high speed development of China's economic construction has promoted the urban construction of China, and the cable well lid that the sewage manhole cover of using in the town and country construction, tap water well lid, electric industry, telecommunications are used etc. is the critical facility in the urban construction.Existing well lid all is to adopt metal to make basically, and cast iron especially is because of the material property of cast iron is doomed himself defective, big as fragility, easy-to-rust, impact resistance is poor, in addition because of cast iron weight is big, and well lid all to be manpower basically install, so the bothersome inconvenience of effort will be installed.The well lid that also has adopts glass fiber reinforced plastic or cement material, though glass fibre reinforced plastic manhole covers intensity height, cost is too high, and ageing resistace and fireproof performance are relatively poor; Low and the not shock resistance of cement well lid bulk strength, easily broken, influence urban traffic safety.
In order to address the above problem, the plastics well lid of built-in reinforcing bar injection mo(u)lding has appearred, when reinforcing bar is band steel, form the well lid skeleton after adopting the band steel clamping, when reinforcing bar is the rounded reinforcing bar in cross section, reinforcing bar intersected places in the well lid for latticed skeleton.Adopt the skeleton of said structure mainly to have following problem: when one, adopting flat steel framework, improved amount of reinforcement, and flat steel framework is to the poor adhesive force of injection molding material, damping property is low; Though two, adopt the circular steel rod-mesh skeleton to solve the problem of poor adhesive force, damping property is low, the problem of high material consumption but exist; Three, adopt the assembling of flat steel framework and circular steel rod-mesh skeleton dumb, cage construction is single.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above that existing manhole well lid exists, and a kind of monolithic well lid steel frame is provided.The utility model adopts multilayer to strengthen, and in conjunction with shock-damping structure, has solved the low problem of existing well lid damping property, strong shock resistance, and can increase the skeleton number of plies when the moulding according to actual conditions, assembling is flexibly.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of monolithic well lid steel frame, comprise and be latticed reinforcing rib layer, it is characterized in that: be provided with many and be undulatory reinforcing rib between reinforcing rib layer and reinforcing rib layer, the crest of reinforcing rib and trough are connected to form undulatory buffer layer with the reinforcing rib layer respectively.
Described buffer layer is one or more, can increase or reduce reinforcing rib buffer layer quantity according to actual needs, thereby regulate the damping property and the impact resistance of well lid.
The crest of described reinforcing rib and trough are welded on the horizontal reinforcing rib in the reinforcing rib layer and the intersection point place of waling respectively, make well lid reach best damping effect.
The rounded or rectangle in reinforcing rib cross section in the described buffer layer, welding fabrication is simple and convenient.
Advantage of the present utility model is:
One, the utility model adopts multilayer to strengthen, and in conjunction with shock-damping structure, has solved the low problem of existing well lid damping property, strong shock resistance, and can increase the skeleton number of plies when the moulding according to actual conditions, assembling is flexibly, and when the moulding well lid, improved the adhesive power of injection molding material.
Two, in the utility model, buffer layer is one or more, can increase or reduce reinforcing rib buffer layer quantity according to actual needs, thereby regulate the damping property and the impact resistance of well lid.
Three, the crest of the utility model reinforcing rib and trough are welded on the horizontal reinforcing rib in the reinforcing rib layer and the intersection point place of waling respectively, make well lid reach best damping effect.
Four, the rounded or rectangle in reinforcing rib cross section in the utility model buffer layer, welding fabrication is simple and convenient; Adopt latticed reinforcing rib layer, can improve bending resistance compressive strength, can save material again.

The specific embodiment
A kind of monolithic well lid steel frame, comprise and be latticed reinforcing rib layer 1, reinforcing rib by vertical bar shaped is welded into latticed, adopt fenestral fabric, it is higher to solve bending resistance compressive strength, save material again, be provided with many and be undulatory reinforcing rib between reinforcing rib layer and reinforcing rib layer, the crest of reinforcing rib and trough are connected to form undulatory buffer layer 2 with reinforcing rib layer 1 respectively.Reinforcing rib layer and reinforcing rib layer link by joint 3, with joint 3 welding, in order to satisfy process, can increase joint 3 thickness respectively.And the crest of reinforcing rib and trough are welded on the horizontal reinforcing rib in the reinforcing rib layer 1 and the intersection point place of waling respectively, make well lid reach best damping effect.The rounded or rectangle in reinforcing rib cross section in the buffer layer 2, welding fabrication is simple and convenient.
Wherein, buffer layer 2 is one or more, and when being a buffer layer 2, the utility model internal layer is a reinforcing rib layer 1, and the intermediate layer is a buffer layer 2, and skin is a reinforcing rib layer 1.When being two buffer layers 2, the utility model internal layer is a reinforcing rib layer 1, and the second layer is that 2, the three layers of buffer layers are that the reinforcing rib layer is a buffer layer 2 for 1, the four layer, and skin is strong muscle layer 1.Can increase or reduce reinforcing rib buffer layer 2 quantity according to actual needs, thereby regulate the damping property and the impact resistance of well lid.
Obviously; those of ordinary skill in the art is according to technological know-how of being grasped and customary means; according to above said content, can also make the various ways that does not break away from the utility model fundamental technics thought, these pro forma conversion are all within protection domain of the present utility model.
